I've installed ZM 1.24.2 on a Ubuntu 10.04 LTS unit following the Wiki http://www.zoneminder.com/wiki/index.ph ... x)_Desktop

I'm using a 4 channel 25 FPS Capture Card with a single 878a chip, and Swann PNP-150 cameras. Just cannot seem to get any video from either camera. Tried them one at a time on channel 0. Tried many different combinations. Went to very basic settings as follows:

Monitor - Monitor-1 (1)
GeneralSourceTimestampBuffersMisc
Device Path /dev/video0
Capture Method Video for Linux version 1
Device Channel 0
Device Format NTSC
Capture Palette Grey
Capture Width (pixels) 320
Capture Height (pixels) 240
Preserve Aspect Ratio
Orientation normal

Here is another output:

in the ZM console the screen is blank but has State: Idle - 30.74 fps below the black screen. I can lower the frames per second and it will correspond to show it. looks like it really wants to work but needs some additional setting.

Any help or ideas would be greatly appreciated.

Your card has been misidentified as "0". You will need to figure which it really is and adjust in bttv.conf. Have a read: http://www.zoneminder.com/forums/viewto ... 14&t=17872

Try creating /etc/modprobe.d/bttv.conf file with this in it:


Code:
# BTTV Modules options
# For fast loading
options i2c-algo-bit bit_test=1

# Pico2000 clone, 4 inputs 1 chip
options bttv gbuffers=16 card=77 radio=0 tuner=4 chroma_agc=1 combfilter=2 full_luma_range=1 coring=1

No change from with original settings in ZM console. Screen is still black. Tried the camera settings: PAL 576x432 BGR24. Screen turns to a nice shade of blue.

$ lspci shows 01:09.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)

I do not see the Brooktree listed on http://tldp.org/HOWTO/BTTV/cards.html

Yet it is mentioned on this page: http://www.zoneminder.com/wiki/index.php/Pico2000

Chip history
The Conexant Fusion 878A is the newer version of the Brooktree Bt878A.

Looks like I just need to figure out what card number to set it to in bttv.conf file that I just created since card=77 did not change anything.

Any additional help or ideas will be greatly appreciated.

In this case identifying the card will be the key since it wasn't automatically. Can't seem to get the link to photos of cards but it does exist, try searching external to this site. Also I believe this has links (2nd url) to posts that outline the bttv number identifier for bttv.conf: http://www.zoneminder.com/forums/viewto ... 21&t=18130

Replaced the 4 port video adapter (Pico2000)
